Mayden, Springfield, IlL, assignor of one-half to Theresa E. Mayden, Springfieid, Ill. Filed Nov. 18, 1965, Ser. No. 508,525 6 Claims. (Cl. 401-470) ABSTRACT OF THE DISCLOSURE A paint applicator including an extension handle from one end of which the applicator is supported and provided with pressurized paint conduit means operatively removably communicated with the paint applicator at one end and with the other end thereof disposed adjacent the end of the extension handle remote from the applicator and adapted for communication with a suitable source of paint under pressure.

This invention relates to a novel and useful paint applicator and more specifically to a fountain brush-type applicator including an extension handle.

The applicator includes an elonagted handle assembly including means defining a paint supply conduit extending longitudinally thereof and having one end portion which is adapted to be grasped by one hand of a painter with the corresponding end portion of the paint supply conduit being adapted to be communicated with a suitable source of paint under pressure, including manually operable control valve means operative to control the flow of paint through the inlet end of the paint supply conduit and adapted to be grasped by the other hand of a painter.

The other end of the handle assembly includes a pair of oppositely and laterally directed support arms terminating at their remote free end portions in right angulated generally parallel and opposing terminal end portions extending away from the handle end portion of the handle assembly. The adjacent end of the paint supply conduit includes an outlet neck portion opening in the same direction in which the terminal end portions project and an elongated brush body is disposed between the free ends of the terminal end portions and is supported therefrom. In addition, the brush body includes brush bristles which project laterally outwardly therefrom and a manifold conduit member extending longitudinally of the brush body and having a plurality of apertures formed therein at points spaced longitudinally thereof Opening outwardly of the conduit member adjacent the base ends of the brush bristles. Still further, the manifold conduit member inv cludes an inlet neck portion projecting toward and disposed in end abutting relation with the free end of the outlet neck portion of the paint supply conduit and a coupling member carried by the last-mentioned neck portion is threadin'gly engaged with the neck portion carried by the manifold conduit member to form a fluid-tight seal between the opposing neck portions.

There are many types of fountain brush paint applicators provided with extension handle assemblies, but which include only minimum bracing between the handle portion of the applicator and the paint brush portion thereof resulting in an apparatus which is subject to frequent repair. In addition, many previous types of fountain brush paint applicators including extension handle portions do not include means whereby the applicator portion of the assembly may be readily removed for cleaning purposes or replacement when desired.

The main object of this invention is to provide a brush and fountain type paint applicator including an extension handle assembly and which includes ample bracing between the paint applying brush portion thereof and the extension handle portion.

Another object of this invention is to provide a paint applicator in accordance with the preceding object and including novel means whereby a sturdy but readily releasable connection between the brush-type applicator and the handle portion of the assembly is provided.

Still another object of this invention is to provide a paint applicator including means by which the fountain-type brush head thereof may be readily connected to and dis connected from operative communication with a suitable source of paint under pressure.

A final object of this invention to be specifically enumerated herein is to provide a paint applicator in accordance with the preceding objects which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble-free in operation.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of the paint applicator of the instant invention;

FIGURE 2 is an enlarged fragmentary vertical sectional view taken substantially upon a plane passing through the longitudinal centerline of the paint applying brush portion of the paint applicator;

FIGURE 3 is a transverse vertical sectional View taken substantially upon the plane indicated by the section line 3-3 of FIGURE 2;

FIGURE 4 is an enlarged fragmentary vertical sectional view taken substantially upon the plane indicated by the section line 44 of FIGURE 2.

Referring now more specifically to the drawings, the numeral generally designates the paint applicator of the instant invention which may be seen to include an elongated handle assembly generally referred to by the reference numeral 12 and which is externally threaded on one end as at 14. The threaded end portion 14 of the handle assembly 12 is threadedly engaged in a threaded socket 16 provided therefor in a fitting body 18 including a pair of right angulated bores 20 and 22 which have adjacent ends in direct communication with each other. The bore 22 is formed in an inlet neck portion 24 of the body 18 and the bore 20 is formed in an outlet neck portion 26 of the body 18 including a circumferential flange 28 at its free end.

A paint supply conduit 30 is supported from the handle assembly 12 by means of a pair of clamp brackets 32 and 34 rigidly interconnecting the handle assembly 12 and the conduit 30 at points spaced longitudinally therealong. The conduit 30 includes an inlet end 36 which is secured to the outlet neck portion 38 of a control valve assembly 40 by means of a suitable fitting 42. The control valve 40 is of course operable to control the flow of paint therethrough from the paint supply line 44 operatively connected to the inlet end portion 46 of the control valve 40.

The outlet end portion of the conduit 30 is secured in the bore 22 formed in the inlet neck portion 24 and in this manner paint from the paint supply line 44 may be conveyed through the control valve 40 and the conduit 30 into the bore 20 formed in the outlet neck portion 26.

The paint applicator additionally includes a paint applying assembly generally referred to by the reference numeral 50 and which may be also said to include the fitting 26. The fitting 26 includes a pair of oppositely and laterally outwardly directed support arms 52 and 54 which terminate at their outer ends in right angulated generally parallel and opposing terminal end portions 56 and 58, respectively.

The free end of the terminal end portion 58 includes a laterally directed stub shaft 60 which projects toward the terminal end portion 56 and the latter includes a retractible stub axle shaft portion 62 which projects toward the terminal end portion 58 and is yieldingly urged to the position illustrated in FIGURE 2 of the drawings by means of a compression spring 64 bearing against an outer end wall 66 at one end and an abutment washer 67 carried by the stub shaft portion 62 at the other end. The outer end wall 66 comprises a part of a housing 68 secured to the end portion 56 in any convenient manner and through which the stub shaft portion 62 is reciprocal, the end portion of the stub shaft portion 62 remote from the stub shaft portion 60 being provided with a knob 70 disposed outwardly of the housing 68 and engageable by the user of the paint applicator 10 to withdraw the stub axle portion 62 outwardly of the terminal end portion 56 and into a position with the inner end of the stub axle portion 62 fully retracted within the bore 72 in the terminal end portion 56 through which the shaft portion 62 is reciprocal.

The assembly 50 also includes a brush applicator generally referred to by the reference numeral 74 including an elongated body portion 76 whose opposite ends are provided with oppositely opening blind bores 78 and 80 in which the adjacent ends of the stub shaft portions 60 and 62 are receivable. The body 76 has a plurality of brush bristles 82 which project outwardly therefrom and a paint manifold pipe or conduit 84 extends longitudinally of the body 76 and is provided with a plurality of small diameter apertures 86 which open outwardly adjacent the base ends of the bristles 82 for conveying paint from the manifold pipe or conduit 84 to the bristles 82. The conduit 84 includes an inlet neck portion 87 which extends through a centrally disposed bore 88 formed in the body 76 and is externally threaded as at 90, see FIG- URE 4, and whose free end abuts against the open end of the outlet bent .portion 26. The coupling member 94 is held captive on the outlet neck portion 26 and is internally threaded and removably threadedly secured to the threaded portion 90 on tthe inlet neck 87 in a manner such that a fluid-tight coupling is formed between the inlet neck 86 and the outlet neck portion 26.

In operation, the paint applicator 10 may be grasped at the end of the handle assembly 12 thereof remote from the brush body 76 and that the control valve 40 will by one hand be utilized to control the fiow of fluid through the control valve 40 and to the manifold pipe or conduit 84 from where the paint will pass outwardly of the apertures 86 and onto the base ends of the bristles 82.

The arms 52 and 54 are constructed of stiff but resilient material and may be flexed when the brush body 76 is supported therefrom in order to apply a thrust on the brush body 76 urging the inlet neck portion 87 thereof into tight frictional engagement with the outlet neck portion 26. Actually, if a suitable resilient seal is provided between the opposing ends of the inlet neck portion 86 and the outlet neck portion 26, the coupling member 94 may be omitted due to the axial thrust applied to the inlet neck portion 86 urging it into tight frictional engagement with the outlet neck portion 26 by means of the resiliency of the arms 52 and 54. Of course, when it is desired to clean or replace the brush body 76, the coupling member 94 may be unscrewed and the knob 70 may be pulled outwardly of the terminal end portion 56 so as to retract the inner end of the stub axle portion 62 from within the blind bore 80.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
